Remark: Specifications above. tested in RF Field Strength environment less than 3 V/M & frequency less than 30 MHz only
Frequency Weighting Network* Characteristics A & C
* Weighting : Characteristics simulated in response to “Human Ear Listing”
Usually, when measuring environmental noise levels, always select the A weightingWeighting C: Characteristics close to the response “FLAT”. Typical, suitable for checking engine noise (Q.C.check) & knowing the sound pressure level of the equipment being tested.
Data storageTo freeze measurement values
Peak holdTo maintain the peak measured value (max.)
Time weighting (Fast & Slow)* Fast – t= 200 ms The “Fast” range is simulated by weighting human ear response times
* Slow – t = 500 ms The “slow” range is easy to get the average sound vibration level
Range selector* Auto range: 30 to 130 dB
